ROTRY KILN.

i Specification of Letters Patent.

Patented March 19, 1907.

Application filed March 29,1906. Serial No. 308,790.

To all whom t may concern,.-

Be it known that I, WILLIAM R. WARREN, a citizen of the United States,residing at Manhattan borough, in the county and State of New York, haveinvented new and useful Improvements in Rotary Kilns, of which thefollowing is a specification. j

This-invention relates to a kiln which can be tilted or adjusted todesired angle and the tilt or inclination varied or set Without stoppingthe rotation or operation.

This invention is set forth in the following specification and claimsand illustrated in the annexed drawing, in which- Figure l is a sideelevation of a kiln embodying this invention. Fig. 2 is a section along:r Fig. l. Fig. 3 is an end view of Fig. 1. Fig. 4 is a section alongyy, Fig. 1.

The kiln is shown with gear-ring b and driving wheel or gear c. Atilting or rocking support d is made to support portions of the kiln.

Screw supports or jacks e at suitable points along the kiln can beadjusted to vary the inclination or tilt thereof. As the kiln is tiltedthe support d is likewise rocked, and engagement of the driving parts ismaintained. The operation or rotation is thus not interfered with by thetilt or adjustment.

By means of this invention it is possible to vary from time to time therate of speed of material passing through the kiln.

The rocking support shown adjacent to the fuel-inlet extremity of thekiln is of material advantage in permitting the kiln to be set up in anylocality without requiring preliminary preparation of a base orfoundation construction or a pivot-bearing support. The rocking of thekiln produces very little movement at the point where the drivingkiln cis located, so that a belt-and-pulley connection actuating the gear cwill not be disarranged. It will also be observed that the inlet end ofthe kiln remains at a uniform level to maintain communication with thestationary feed means or hopper.

What I claim asmy invention, and desire to secure by Letters Patent, is

l. A kiln having a rocking support at the inlet or supply end, thelatter end remaining at a uniform level.

2. A kiln having driving or rotating means, a rocking vsupport at thesupply end, the supply end of the kiln remains at a uniform level, andmeans for tilting or adjusting the inclination of the kiln.

3. A kiln having driving or rotary means, a rocking support at the inletor supply end of the kiln, and screws for adjusting the remainingportion of the kiln to vary the inclination of the latter.

In testimony whereof I have hereunto set my hand in the presence of twosubscribing witnesses.

WILLIAM R. WARREN. Witnesses:

EDWARD WIEsNER, GEORGE HULSBERG.
